Description

The present invention relates to a lamp, in particular a portable lamp, comprising a base body which forms a lower region of the lamp, an at least partially transparent light chamber wall which is arranged above the base body and surrounds a light chamber, and a light source and / or a receptacle for an electric light source, wherein the light source and / or the receptacle are arranged such that the light source or a light source inserted or insertable into the receptacle can emit light through the light chamber wall into the surroundings. Lamps, especially electric lamps, are used in various fields. One possible application is outdoor activities where an autonomous and portable light source is required. Petroleum lamps, for example, are known from the prior art. These typically comprise a base containing a reservoir for liquid petroleum. They also usually have a combustion chamber enclosed by a transparent wall. A petroleum flame burns inside this chamber and emits light through the wall into the surrounding area. Such petroleum lamps typically have a lid that forms the upper boundary of the combustion chamber and to which a carrying handle is attached. Besides traditional kerosene lamps, portable lamps with an electric light source or a socket for one are becoming increasingly common. This has the advantage that a simple battery or rechargeable battery can be used as an energy storage device instead of liquid kerosene, resulting in greater reliability and safety. Although such portable lamps have generally proven their worth, there is still room for improvement. Against this background, the object of the present invention is to create an alternative lamp, in particular a portable lamp, which is characterized in particular by favorable properties and simple and safe usability. This problem is solved in a lamp of the type mentioned at the outset according to a first aspect of the present invention in that the base body is made of a metallic material, in particular of aluminium or an aluminium alloy, and / or that the base body is a casting or comprises one. This aspect of the invention is based on the fundamental idea of ​​designing the base body from a metallic material, resulting in a robust design particularly suitable for outdoor activities. It has been found that such a metallic material, especially aluminum or an aluminum alloy, is significantly more robust than, for example, base bodies made of plastic. Furthermore, it offers a more sophisticated appearance. Manufacturing the base body as a casting allows for cost-effective and efficient production. According to a second aspect of the present invention, the underlying problem of a lamp of the type mentioned at the outset is solved by the fact that the lamp has a rechargeable energy storage device and connection means for a power source and a consumer, so that the energy storage device can be charged by connecting to a power source and / or a connected consumer can be supplied with power from the energy storage device. The lamp is preferably designed such that, in particular optionally, the lamp can be operated with a connected power source without simultaneously supplying a consumer with electrical energy, and the lamp can be operated with a connected power source while simultaneously supplying a connected consumer with electrical energy, and the lamp can be operated without a connected power source while simultaneously supplying a consumer with electrical energy, and the lamp can be operated without a connected power source without simultaneously supplying a consumer with electrical energy. In other words, according to the second aspect of the present invention, the lamp can be used in various operating modes. The lamp contains a rechargeable energy storage device, which is preferably housed in the base. The energy storage device can comprise or consist of one or more lithium-ion batteries. A power source and / or a load can be connected via appropriate connection means. The lamp can be operated either with or without a connected power source. If a power source is connected, the rechargeable energy storage device can be charged. If the lamp is operated without a connected power source, the electrical energy required to operate the light source is drawn from the energy storage device.Simultaneously, an external device, such as a mobile phone or tablet, can also be powered by the rechargeable energy storage device. This means that such devices can be connected to the lamp to charge or operate it. This can occur with or without a connected power source. In other words, according to the second aspect of the present invention, the lamp can be operated very flexibly depending on the current requirements and can be used not only as a lamp but also as a power bank. In a specific embodiment, the connection means can have an input port for connecting to a power source, in particular the mains power supply, and at least one, and exactly one, port for a consumer, preferably for a mobile phone or a tablet. The input port and at least one output port, and in particular each output port, can be identical. Specifically, the input port for a power source and / or at least one, and in particular each, output port for a consumer can be configured as a USB port, in particular as a USB-C port. The input port for a power source can be configured to be charged with a supply voltage of 5 V and / or 9 V and / or 12 V. At least one, and in particular each, output port for a consumer can be configured to provide a voltage of 5 V and / or 9 V and / or 12 V to a consumer.The input terminal for a power source and / or at least one, and in particular each, output terminal for a load can be configured to operate at a specific voltage, e.g., 5 V, 9 V, or 12 V. It is also possible for the input and / or output terminals to be designed as so-called smart slots, which can be used with different voltages, for example, 5 V, 9 V, or 12 V. Preferably, the supply voltage and / or the voltage provided to a load is a DC voltage. The connections can be arranged in recesses in the base body. In particular, the connections can be located on a circumferential surface of the base body. To protect against contamination, the connections can be provided with cover elements. Preferably, the cover elements can be made of an elastomer and / or be held in place on the base body to prevent loss of the cover elements. Appropriate markings can be provided adjacent to the connections to identify each connection as an inlet or outlet. The lamp can have a status indicator designed to display information about the charge level of the energy storage device, particularly when a power supply is connected. This allows the user to see when the energy storage device is fully charged and the lamp can be disconnected from the power supply. In a specific embodiment, the status indicator can include a status light, especially an LED. This can be located in close proximity to the input terminal, in particular such that the status light is also covered by the cover when it is in place. The arrangement can be such that the indicator light flashes when the lamp is connected to a power source and the energy storage device is not fully charged, and that it remains illuminated when the lamp is connected to a power source and the energy storage device is fully charged. In other words, a control device for the lamp can be connected to the indicator light and configured such that the lamp flashes as long as the energy storage device is not fully charged when the lamp is connected to a power supply, and that the indicator light remains illuminated when the energy storage device is fully charged and the lamp is connected to a power supply. Preferably, the indicator light illuminates only when the lamp is connected to a power supply. According to a third aspect of the present invention, the problem in a lamp of the type mentioned at the outset is solved by the fact that the lamp has an adjusting device which is designed to adjust the intensity and the color of the light source or of a light source inserted or insertable into the receptacle. This design is based on the idea of ​​being able to adjust the intensity (i.e., brightness) and color temperature of the light source depending on the application. In other words, the lamp can have a control unit that processes a signal provided by the actuator and accordingly controls the light source, or a light source inserted into the fixture, in such a way that the intensity and color temperature of the light source are specified. In a specific embodiment, the adjusting device can include a handwheel or be designed as a handwheel. Preferably, the handwheel is held on the base body, in particular rotatably mounted on the base body about a handwheel axis of rotation. The handwheel can be moved towards and / or away from the base body along a handwheel axis of rotation. This embodiment is based on the consideration of preferably creating two adjustment possibilities: firstly, rotating the handwheel about the handwheel axis of rotation, and secondly, moving the handwheel towards and / or away from the base body. This makes it possible to adjust two parameters, for example, the intensity and the color temperature of the light source, independently of each other. Preferably, with regard to the translational movement towards or away from the base body, the handwheel is designed like a push button.Specifically, the handwheel can be pre-tensioned along its axis of rotation, for example by means of a spring, towards a starting position, so that pressing the handwheel against the base can trigger a signal. Releasing the handwheel can cause it to return to its starting position, so that it functions practically like a push button. In a further embodiment, the handwheel can interact with the light source or with a light source inserted or insertable into the fixture in such a way that rotating the handwheel around its axis of rotation results in a particularly stepless change in the intensity of the light emitted by the light source. The handwheel can also interact with the light source or with a light source inserted or insertable into the fixture in such a way that pushing the handwheel towards the base body results in a particularly discrete change in the color temperature of the light emitted by the light source. In other words, the intensity of the light source can be adjusted practically steplessly by rotating the handwheel. A change in the color temperature is also possible, preferably discrete, i.e., in predefined steps. Possible color temperature steps could be 2200 K, 3000 K, and 5000 K.In a specific design, the handwheel rotation axis can extend radially to a basic axis of the lamp defined by the base body. The problem underlying the invention is solved, according to a fourth aspect, in a lamp of the type mentioned at the outset, by the fact that the lamp has a display device configured to show information about the lamp's state. This design is based on the consideration of providing the user with a way to obtain information about the lamp's state by means of a suitable display device. Thus, a control unit can transmit or provide corresponding information to the display device. Preferably, the display device is configured to show information on the color of the light emitted by a lamp, the intensity of the light emitted by a lamp, the charge level of an energy storage device integrated into or connected to the lamp, and / or the lamp's potential operating time, particularly based on the energy storage device's charge level. In other words, various pieces of information can be displayed on the display device simultaneously or sequentially, and selectively. This information can include the color of the light or the intensity of the light emitted by a lamp. Information on the energy storage device's charge level is also possible. This can be displayed as a percentage relative to a full charge and / or as the remaining operating time.According to a preferred embodiment, the display device is held on the base body, projecting outwards from the base body. Specifically, the display device can be mounted on the base body as a top-mounted element. For example, the display device can be designed stylistically like a classic pressure gauge and / or mounted externally on the base body, in particular screwed to it. The display device can have a housing, which is mounted, in particular, on a tapered section of the base body. The display device can, in particular, project radially outwards and / or obliquely upwards with respect to a central axis. The display device can have an electrical display, in particular a segment display. It is also possible for the display device to have a display, which is particularly circular in shape. To be able to display different information selectively, the display device can have corresponding control means. These can include a control knob, preferably arranged such that turning the control knob changes the information displayed on the display device. Specifically, it is possible to switch between several different pieces of information, in particular the four mentioned above, by turning the control knob. The control knob can be arranged laterally on a display device housing. The display device can have a light source so that the displayed information can be read even in dark environments. The various aspects or features of the invention can also be combined in any way desired. Preferred embodiments of a lamp according to any one or more of the aspects mentioned above or below are described below. The lamp can have a light source inserted into the housing. This design is based on the consideration that such a lamp can be provided with a permanently integrated light source. Such a light source can be permanently connected to the lamp, which is particularly advantageous for light sources with a long lifespan. This allows the lighting compartment to be enclosed, meaning that a user may not have any external access to the lighting compartment, which is preferably completely surrounded by a wall. It is also possible that the lamp has a receptacle for an electric light source, whereby the light source is replaceable. In this case, the lamp can be provided without a light source, and a user can insert or replace a suitable light source. It is also conceivable that the lamp according to the invention has a receptacle for a light source and that a light source is already inserted into this receptacle. The light source can be an LED light source. This type of light source is particularly energy-efficient and especially suitable for use with a rechargeable battery. Furthermore, an LED light source has a long lifespan. The LED light source can consist of one or more light-emitting diodes. This design as an LED light source is independent of whether it is permanently integrated into the lamp or inserted into the socket. In a further embodiment, the light source can be designed to emit light with a color temperature of at least 1000 K and / or at most 8000 K. The light source can be designed to emit a maximum luminous flux of at least 500 lumens. In other words, with appropriate adjustment of the control device, the light source can emit a high luminous flux of more than 500 lumens, so that the lamp provides favorable illumination of the surroundings. The base body and / or the walls of the light chamber can be designed to be at least substantially rotationally symmetrical. The wall of the light chamber can be annular and / or cylindrical, in particular circular-cylindrical. It is also possible for the wall of the light chamber, which is preferably rotationally symmetrical, to taper upwards. Specifically, the wall of the light chamber can taper slightly upwards, for example with an angle of inclination of less than 10°, in particular less than 5°, relative to a central axis. The wall of the light chamber can completely encircle the light chamber, in which the light source or a receptacle for a light source may be located. The light source or a receptacle for a light source can be arranged on the base body and / or switched. The light chamber wall can be made of glass, in particular transparent or semi-transparent glass. It is also possible, in principle, for the light chamber wall to be made of transparent or semi-transparent plastic. The lamp according to the invention can further comprise a cover which adjoins the upper wall of the light chamber and, in particular, defines the upper boundary of the light chamber. In other words, a cover can be provided above the wall of the light chamber, i.e., on the side opposite the base body. This cover can be at least substantially rotationally symmetrical and / or made of a metallic material, in particular aluminum or an aluminum alloy. Such a design made of a metallic material is particularly robust, especially compared to a design made of plastic. Furthermore, such a design results in a high-quality external appearance. The cover can be a cast part. This leads to simple and cost-effective manufacturing. The cover and the base body can be connected to each other by suitable connecting means. These can comprise several, in particular exactly three, four, or six, connecting rods distributed around the circumference, which are connected to the base body on one underside and to the cover on the other. The connecting rods can extend outside the light chamber wall and / or at least substantially perpendicularly from the base body to the cover. In other words, several connecting rods can be provided that extend between the base body and the cover and connect these two components. The light chamber wall can accordingly be arranged between the cover and the base body, in particular clamped between them. For this purpose, the base body and / or the cover can have suitable recesses into which the light chamber wall engages. In a specific embodiment, the base body can have a ring collar at one upper end, and the lid can have a corresponding counter collar at one lower end. The connecting rods can be connected to the ring collar and the counter collar. Specifically, the connecting rods can be bonded to the base body, in particular to the ring collar, and to the lid, in particular to the counter collar, by a material-fit and / or form-fit connection, in particular by screwing, pressing, welding, and / or soldering. Furthermore, the lamp can have a carrying handle, which is rotatably mounted on opposite sides of the lid. For this purpose, corresponding retaining projections can be formed on the lid, which the carrying handle preferably engages. The carrying handle can be formed by a substantially U-shaped metal rod, in particular an aluminum rod and / or a steel rod. To selectively activate or deactivate the light source or a light source inserted into the fixture, the lamp can be equipped with appropriate switching devices. Specifically, the switching devices can include a push button that can be pressed to activate or deactivate a light source. In particular, the push button can be attached to the cover and preferably inserted into a recess, especially one located centrally on the top surface. A control unit can receive and process a signal provided by the switching devices. Depending on the signal from the switching devices, the control unit can control the light source and activate or deactivate it accordingly. According to a further aspect of the present invention, a lamp of the type mentioned at the outset can be designed such that, after activation of the light source or a light source inserted or insertable into the fixture, the light source is controlled for a defined period and / or continuously in such a way as to simulate light with fluctuating intensity and / or color, thus mimicking the flickering of a candle or a kerosene lamp. This allows for the achievement of lighting behavior similar to that of a classic kerosene lamp. In other words, the lamp can have a control device suitable for controlling a light source in such a way that it emits light with fluctuating intensity and / or color, thereby simulating flickering. This flickering can extend for a defined period immediately after switching on, for example, a few seconds, or occur continuously.A changing intensity corresponds to a changing brightness, whereas a changing light color varies the hue of the emitted light. For further details, reference is made to the dependent claims and the following description of an exemplary embodiment with reference to the drawing. In the drawing: Fig. 1 shows a lamp according to the present invention in a perspective view; Fig. 2 shows the lamp from Fig. 1 in a side view; Fig. 3 shows the lamp from Fig. 1 in a perspective view, with the energy storage device shown schematically; Fig. 4 shows a partial area of ​​the base body of the lamp from Fig. 1 in a perspective view, wherein the connections are closed by a cover element; Fig. 5 shows the arrangement from Fig. 4, wherein one connection is not closed by a cover element; Fig. 6 shows a detailed view of an area of ​​the base body of the lamp from Fig. 1 with a display device in a perspective view; and Fig. 7 shows a partial area of ​​the base body of the lamp from Fig. 1 with an adjustment knob in a side view. Figures 1, 2, 3, 4, 5, 6 to 7 show a portable lamp 1 according to the present invention in various views. The lamp 1 comprises a substantially rotationally symmetrical base body 2, which forms a lower region of the lamp and defines a central axis Y. The base body 2 is a cast part made of an aluminum alloy. On one underside, the base body 2 has an annular base collar 3, which forms a support surface for the lamp on a base. Above the base collar 3, a lower cylindrical section extends, followed by a tapered section 5 and another upper cylindrical section 6. Furthermore, the base body 2 has a radially outwardly projecting annular collar 7 at its upper end. Furthermore, the lamp 1 includes a ring-shaped, cylindrical light chamber wall 8, which in this case consists of partially transparent glass. The light chamber wall 8 is arranged above the base body or inserted into it from above and surrounds an inner light chamber. The lamp 1 further comprises a cover 9, which defines the upper boundary of the light chamber and is placed on the wall of the light chamber 8. The cover 9 is essentially rotationally symmetrical and is made of an aluminum alloy. On one underside, the cover has a counter-rib 10 corresponding to the ring collar 7. The cover 9 comprises two opposing retaining projections 11, to which a support bracket 12 with a U-shaped base is pivotably held. In its center, the support bracket 12 has a recess 13 for suspending the lamp 1. The cover 9 and the base body 2 are connected to each other by suitable connecting means. Specifically, the connecting means 4 comprise connecting rods 14 distributed around the circumference, which are connected, specifically welded, to the ring collar 7 of the base body 2 on one underside and to the corresponding collar 10 of the cover 9 on one upper side. The connecting rods 14 extend outside the light chamber wall 8 and perpendicularly, i.e., parallel to the central axis Y. Lamp 1 also has an electric light source, which is not shown in detail in the figures. The light source is inserted into a receptacle on the top of the base body 2, so that it can emit light through the light chamber wall 8 into the surroundings. Specifically, the light source is an LED light source adjustable in terms of intensity and color temperature, designed to emit light with a color temperature of at least 1000 K and at most 8000 K. Furthermore, the lamp 1 has a rechargeable energy storage device in the form of several lithium-ion batteries 15, which are shown in Fig. 3. For charging the energy storage device, the lamp 1 has an input port 16, which is designed as a USB-C port and which is arranged in a recess in the upper cylindrical section 6 of the base body 2. The lamp 1 has an output connector 17, also in the form of a USB-C connector, offset by a circumferential angle of approximately 90° for connecting a device, in particular a mobile phone or tablet. The input connector 16 and the output connector 17 are each provided with a cover element 18 made of elastomer, which is held on the base body 2. In Fig. 4, the two cover elements 18 are inserted into the corresponding recesses of the base body 2, so that the connectors 16, 17 are protected against contamination. Accordingly, the connectors 16, 17 are located under the respective cover element 18 in Fig. 4 and are not visible. In Fig. 5, the cover element 18 for the input connector 16 is pulled out of the recess so that a power source can be connected. The energy storage unit can be charged by connecting it to a power source, especially the mains electricity supply. Separately, a connected device can be powered by the energy storage unit, meaning that Lamp 1 can also be used practically as a power bank. The lamp 1 further comprises an adjusting device designed to adjust the intensity and color of the light source. For this purpose, the adjusting device includes a handwheel 19, which is rotatably mounted on the base body 2 about a handwheel pivot axis X. The handwheel 19 can also be moved along the handwheel pivot axis X like a push button on the base body. A return element, for example in the form of a spring, is provided to return the handwheel 19 to its original starting position after it has been pressed on the base body. The handwheel 19 interacts with the light source in such a way that rotating the handwheel 19 about its axis of rotation X results in a stepless change in the intensity of the light emitted by the light source. Furthermore, the handwheel 19 interacts with the light source in such a way that pushing the handwheel 19 towards the base body 2 results in a discrete change in the color temperature of the light emitted by the light source, specifically switching between color temperatures of 2200 K, 3000 K, and 5000 K. Furthermore, the lamp 1 has a display device 20, which is configured to display information about the status of the lamp 1. Specifically, the display device 20 is mounted as an attachment element on the base body 2 in the area of ​​the tapered section 5. The display device 20 is configured to selectively display information about the color of the light emitted by the lamp, information about the intensity of the light emitted by the lamp, information about the charge level of the energy storage device, and information about the operating time of the lamp 1 based on the charge level of the energy storage device. For this purpose, the display device 20, which is designed as an electrical display, specifically as a segment display, has adjusting means. These include an adjusting wheel 21 which is rotatably arranged laterally on the display device 20.The arrangement is such that turning the adjusting wheel 21 leads to a change in the information displayed on the display device 20. Furthermore, the lamp 1 has switching means to selectively activate or deactivate the light source. Specifically, the switching means include a push button 22, which can be pressed to activate or deactivate the light source. This button is inserted into a recess formed centrally in the top of the cover 9. The metal base 2 and the metal cover 9 result in a robust design for the lamp 1. Furthermore, the connections 16 and 17 allow for flexible use, practically like a power bank, for charging external devices such as mobile phones or tablets. Finally, the handwheel 19 allows for the adjustment of essential parameters of the light source, namely the light color and intensity. The display 20 enables an accurate prediction of the remaining operating time or the charge level of the energy storage device.
